Problem with rendering cookie "_mkto_trk" and pre-fill in _mkt_trk input hidden field.

Did you recently update to the latest version of jQuery on your site? If so, you may need to use munchkin-beta.js instead of munchkin.js. Munchkin-beta is actually now the standard version since the last Marketo release I believe. Let me know if this fixes your issue, and if not, consider posting the URL so the community can help to diagnose the issue.

Actually, I can't find any official documentation right now, but if you go to the Munchkin setup in Admin, you'll find that munchkin-beta is now there by default. Perhaps this was a stealth update. Here's a post from Erik @ Marketo on the matter: "Basically, we're removing the jQuery dependency in order to make it more compatable with other versions of it (like 1.9)."

And another post from Erik mentioning how the beta might fix library conflicts, "I've seen this before myself with other libraries. There are some (including Prototype it seems) which don't always play nice with what is on the page. Now, the beta is more isolated and less likely to have this issue."

I'm not sure what Marketo are planning to do with regards to the naming of munchkin files, but I'd assume using munchkin-beta is safe for everyone now that it is the default option. We've been using it for a while now with no issues.

Hi, 

Here is my site:

Could you have a look what we're using Marketo setup on that.

I went to Munchkin setup in Admin, i found that munchkin.js still by default. 

Thanks

Ok, well you have a TypeError on line 1459 which could be preventing your Munchkin and Google Analytics scripts from being invoked. Once you've resolved that error, you may find that tracking starts working.

Let me know if that solves your issue :)

Actually the one I'm referring to is the line that starts with <script>window.require(["SHARED/base","SHARED/selectors",

and the pasted error:

Uncaught TypeError: undefined is not a function www.exoplatform.com/company/en/products:1459

Hi Adam,

You can test it on http://blog.exoplatform.com , it had the same problem without the javascript errors.

The javascript error:

Uncaught TypeError: undefined is not a function www.exoplatform.com/company/en/products:1459

it doesn't impact to the Marketo's scripts. Because if it impacts to Marketo's scripts, Marketo won't work when we implement it on our sites. Normally, it still works fine, just in some cases, it doesn't work well.
Sometimes it cannot be autofilled the cookie value “_mkto_trk”  to input hidden field “mkt_trk” before we submit the form.

Could you check it on other sites by the way we are testing : remove the cookie "_mkt_trk" and refresh page?

Thanks

Ah, I've just noticed you have some code which manipulates mkto cookies. Apologies, as I haven't had the chance to experiment with this myself. The only thing I can suggest is debug this code as much as you can and create lots of test scenarios. I tested http://www.exoplatform.com/company/en/products by observing that I was cookied, deleting the cookie and refreshing the page: each time I got a different tracking token. Is this working as you'd expect?

One other thing to check is your "Do Not Track" setting in Munchkin Admin: If you're supporting this, it would explain why some leads aren't being tracked.
